The Challenge
Businesses need customer feedback to improve, but collecting it at scale has become increasingly difficult. Traditional survey methods are failing: email surveys see response rates as low as 5-15%, SMS surveys are slightly better but still limited, and in-app pop-ups generate survey fatigue that degrades both response quality and user experience.
Low response rates undermine data quality. When only a small, self-selecting group responds to surveys, the results are biased. Satisfied customers rarely bother, and the most frustrated ones may have already churned. Businesses end up making decisions based on feedback that does not represent their actual customer base. The result is a blind spot in the voice of the customer that can lead to misallocated resources and missed problems.
Manual phone surveys are expensive. Phone surveys consistently achieve the highest response rates, often 30-50% or more, because a live conversation is harder to ignore than an email. But hiring interviewers, training them, managing call campaigns, and processing the results is prohibitively expensive for most organizations. The cost per completed survey with human interviewers can range from $15 to $50 or more, making large-scale phone research a luxury reserved for enterprises with dedicated market research budgets.
Unstructured data is hard to act on. Even when feedback is collected, open-ended responses require manual analysis to categorize, quantify, and surface actionable insights. Teams spend hours reading through comments, tagging themes, and building reports. By the time the analysis is complete, the feedback is often weeks old and the window to act on it has closed.
The Solution with Vocals
Vocals enables you to run phone surveys at scale using AI voice agents that hold natural, conversational interviews with respondents. The AI calls your list, introduces the survey, asks questions in a human-like manner, handles follow-up probes, and captures both structured ratings and open-ended responses. All data is structured in real time and delivered to your systems through webhooks.
Unlike robocall surveys that play pre-recorded messages and ask respondents to press buttons, Vocals agents engage in genuine two-way conversations. Respondents can elaborate on their answers, ask for clarification, skip questions, or provide unsolicited feedback. The AI adapts the conversation flow dynamically, asking follow-up questions when it detects strong sentiment or unexpected responses. This produces richer, more nuanced data than any traditional survey method.
The economics are compelling: AI survey calls cost a fraction of human-conducted phone surveys while achieving comparable response rates and data quality. You can survey thousands of customers in hours rather than weeks, with results available in real time.
Key Features
- Open-Ended Question Handling: Unlike IVR-based surveys that limit responses to numeric ratings, Vocals agents can ask open-ended questions and understand free-form answers. "What could we do better?" becomes a real conversation, not a button press. The AI captures the full response, extracts key themes, and structures the data for analysis. This gives you the depth of qualitative research at the scale of quantitative surveys.
- Real-Time Data Structuring: As each call completes, the AI automatically structures the responses into your predefined schema: ratings, categories, sentiment scores, and extracted themes. Data flows to your analytics tools via webhooks in real time. There is no manual transcription, no coding of responses, no delay between data collection and analysis. You can monitor results as the campaign runs and make adjustments on the fly.
- Sentiment Detection and Adaptive Flow: The AI detects emotional tone during the conversation and adjusts its approach accordingly. If a respondent expresses frustration, the agent can probe deeper, offer empathy, or flag the interaction for immediate follow-up by your team. If a respondent is enthusiastic, the agent can ask for a testimonial or referral. This adaptive behavior produces higher-quality data and a better respondent experience.
- Scalable Campaign Management: Launch surveys targeting hundreds or thousands of contacts with configurable pacing, scheduling, and retry logic. Set calling windows to respect time zones and regulations, configure maximum attempts per contact, and manage multiple concurrent campaigns from a single dashboard. Vocals handles the operational complexity so you can focus on designing great surveys and acting on the results.
How It Works
Running an AI-powered survey campaign with Vocals follows a simple, repeatable process:
- Design Your Survey: Configure your AI agent with the survey introduction, questions, follow-up logic, and closing script. Define the data fields you want to capture (ratings, categories, open-text themes) and the conditions for follow-up probes. The agent's system prompt acts as your survey script, but with the flexibility to handle natural conversation.
- Upload Your Contact List: Import the list of respondents with phone numbers and any contextual data (customer segment, recent purchase, support ticket) that the AI can reference to personalize the conversation.
- Launch the Campaign: Configure calling windows, pacing, and retry rules, then start the campaign. Vocals dials through your list, connects answered calls to the AI agent, and handles voicemails and busy signals automatically.
- AI Conducts the Interview: Each call is a natural conversation. The AI introduces the survey, asks questions in order, handles digressions and follow-ups, captures responses, and thanks the respondent. The entire interaction is recorded and transcribed.
- Data Delivered in Real Time: As each call completes, structured data (ratings, themes, sentiment, transcript) is pushed to your systems via webhooks. You can pipe results directly into your BI tools, CRM, or a custom dashboard for live monitoring.
Why Vocals
AI-powered phone surveys require a platform that combines natural conversation quality with operational scale. Here is why Vocals is the right choice:
- BYOK for Cost Control: Connect your own API keys for STT, LLM, and TTS providers. At survey scale, where you might conduct thousands of calls per campaign, paying provider-direct prices with no markup makes a significant difference in total cost. You control the economics.
- Natural Conversations, Not Robocalls: Sub-2-second latency and high-quality voice synthesis create interactions that respondents actually engage with. The difference between a robocall survey and a Vocals survey is the difference between a 5% and a 35% response rate.
- 32+ Languages: Run surveys across regions and demographics without hiring multilingual interviewers. The AI conducts the survey in the respondent's preferred language, expanding your reach and improving representation in your data.
- 9+ AI Providers: Choose the best combination of STT, LLM, and TTS providers for your survey type. Use a more accurate transcription model for complex open-ended responses, or a faster model for high-volume rating surveys. You have full control over the pipeline.
- Pay Per Minute: No per-survey fees, no respondent minimums. You pay only for actual call minutes, making it cost-effective to run small pilots or large-scale campaigns. Test your survey design with 50 calls before scaling to 5,000.
